Elcometer 506 Pull-Off Adhesion Tester

The design of the Elcometer 506 Adhesion Tester ensures that a uniform force can be easily applied over the entire range by gently rotating the gauge hand, ensuring repeatable adhesion results with an accuracy of ±1%.

With the help of a variety of accessories, the Elcometer 506 adhesion tester’s quick connect coupling enables the quick attachment of 14.2mm, 20mm, or 50mm diameter dollies, enabling coating adhesion testing on flat, curved, thick, and thin substrates like metal, wood, concrete, and other fibrous materials.

The Elcometer 506 test head (actuator) has been designed to be small, ergonomic, and lightweight – ideal for single-handed testing of coating adhesion even in awkward or confined spaces.

Safe adhesion tests on vertical surfaces were also considered. Using the magnetic clamp attachment, the actuator is securely held, preventing accidental damage to surrounding areas.
